A little background:
I've been riding pretty seriously for about six years now, and my high school days are coming to and end here in a few months. While in high school I ran both cross country and Track very competitively. And with those two sports (primarily track and field) came required weight lifting. For four years I lifted ~3 days a week, and with that I got stronger in both my upper and lower body.
I've made the decision not to run in college, and instead do what I love, which is cycling. Now though I'm stuck with quite a bit of unneeded muscles in my shoulders, arms, and back and I'm looking for a way to tone them down.
I'm very lean (6,2-165 lbs) and I feel that loosing some of that muscle mass will benefit my riding.
Any tips would be awesome!
